STIRR'UP.

Specification of Letters Patent No. 30,369, dated October 9, 1860.

ing, making a part of this specification, in wh1ch Figure 1, represents an uprightside View. Fig. 2, shows an edge view, with the position of the step changed, (in dotted lines.)

My invention consists in making stirrups with the step movable on pivots, so that it can vary to any angle or turn over and change sides in the how, the rods or support for the foot being friction rollers, as also the sides of the bow, as high as is necessary for the sides of the foot to bear against, thereby making it an antifriction stirrup.

To enable others skilled in the art to make and use my invention, 1 will describe it, referring to the drawings and the letters marked thereon.

The bow (A, A,) may be made of iron or steel rods, bent in any required form and of any size desired, the lower ends having eyes (a, (0,) in which to secure the step (13.) On each side of the bow (A, A,) are rollers (Z), 7),) one or more in number, which may be made of metal tube or of any equivalent ma terial to prevent friction. The step or foot piece (B) is made by having two end pieces (C, C,) which are pivoted to the eyes (a, C6,) by set screws (0, 6,) fitted into them, they being connected together by two or more rods (D, 1),) which of themselves may form friction rollers, or they may have tubes of metal or any equivalent covering that will be antifriction, so as to liberate the foot, the step (B,) being pivoted on the center of the pieces (C, (1,) so as to balance, and will vibrate or turn either way, and will take any inclination to suit the position of the foot, while the rollers (b, 6,) on the sides of the bow (A, A preventwear to the shoe and serve to liberate the foot, so that it cannot hang, by being turned or cramped in the stirrup should the rider be unhorsed. It is a lamentable fact that very many serious accidents occur by persons being thrown from the saddle and the foot being caught and held, by the rigidity and roughness of the stirrup.

By my peculiar construction of the movable step and the arrangement of the fric- 4 tion rollers on both bottom and sides for the foot to bear against it becomes a most perfeet anti-friction stirrup.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent is- The rotating and oscillating step having friction rollers or their equivalents on both the step and sides of the bow, constructed and arranged in the manner and for the purposes herein specified.

JOHN R. WILLIAMSON.
